That rings a bell: DOS and some versions of Windows won't let you delete 
the directory that's the current directory on some drive, even if you do 
that from another drive.  The trick to overcome that is to chdir to the 
root directory on that drive before removing the temporary directory.

I'm not sure this problem is relevant to the case in point, since I 
understood from Jim's message that the test suite creates the temporary 
directories where you run the suite, not under $TMPDIR (which can 
typically be on a different drive).  But I thought I'd mention this 
caveat anyway, in case some of the tests do use $TMPDIR.

Normally, the "trap ... rm ..." parts of many scripts are vulnerable to 
this problem.
